` PENCIL.

Application filed November 13, 1920.

, To all whom it may concern Be it known that I, l/VILLIAM C. S. MAYs, a citizen of the United States, residing at city of Cranston, inthel county of Provi- I dence and State'of Rhode Island, have invented certain new and useful Improvements in Pencils, of which the following is a speciiication.

This invention relates to improvements in mechanically fed lead pencils, and has for its object to provide an improvement in the construction of lead-propelling pencils, which is simple, practical and inexpensive in construction and which is made of the minimum amount of parts.

The nature and advantages of the invention will be better understood when the following detail description is taken in connection with the accompan ing drawings,

the invention residing in t e combination and arrangement of parts as claimed. l

In the drawings forming part of this specifioatiomlike numerals of reference indicate similar parts in the several views and wherein i Figure 1 'is a sectional side elevation of myimproved pencil. p

Figure 2 is a sectional elevation showing the rotatable unit as removed from the shell of the pencil, which includes the ejector carrier, the magazine, and the operating cap or end.

Figure 3 is a detail illustrating the eraser carrying cup' ywith the. veraser mounted therein.

Figure 4 is a detail illustrating the tube having the ejector'` operating helical slot therein.

Figure 5 isa detail illustrating the lead ejector.

Withreference tothe drawings, 10 designates the outer shell or body of a pencil, whichis pointed at one end as at 11. With-,- in this body is fixed the rigid ejector-operating member 12 which is preferably made in tubular form and provided with a helical groove 13 for receivlng the uttermost end of the e'ector. The lower end 14 of this tube is fixed in a central hole in the collar 15 and this collar in turn is secured to the inner face of the shell by means of pins 16, or otherwise.

A carrier for the ej eotor member is formed Serial No. 423,960,

of the tube 17 having its lower end 18 split as at 19 andsupported by the tapering walls of the shell. This carrier tube extends u through the center of the helical tube 12 whereby this unit which includes the maga-1v zine tube 21 and the ejector carrier 17, may be rotated relative to the outer shell or body 10 and the helix 12.v f

This ejector carrier is'provided with a longitudinally-disposed slot 23 leading inwardly from its upper end and through which slot extends the outturned end 24 of the ejector member 25, the body portion of which ejector is designed to be carried in the tube 17, its lower end being adapted to engage the upper end of the lead 26 in the outer end of the ca-rrierand advance the lead, when desired.

Beneath the lower end of the helix 12 I have formed a protuberance or shoulder 27 which serves to securely lock the ejector carrier tube in position against being drawn outwardly by any movementon the operating handle 22, after the collar 15 at the lower end of the helix has been secured to the walls of the outer shell. In other words the rotatable unit including the cap 22, the magazine 21, and the ejector carrier 17, could all be withdrawn from the shell 1() if it were not for this locking protuberance 27 formed in the ejector tube below the fixed collar 15.`

In some instances it is found to be of advantage to provide a cap 28 which is adapted to fit into the upper end of the magazine chamber 21 and to carry an eraser 29 which `will be exposed for use when cap 22 is withdrawn from its tube 21.

The device is extremely simple, inexpensive and practical in construction.

The foregoing description is directed solely towards the construction illustrated, but I desire it to be understood that I reserve the rivilege of resortin to all the mecham changes to which t e device is susceptible, the invention being defined and limited only by the terms of the appended claims.

l claim:

A pencil comprising an outer shell tapered at one end, a rigid tubular member Within the shell and having a lateral spacing element stationarily secured thereto and extending outivardly therefrom to Contact with the inner Walls of the shell and to maintain said member out of Contact with said Walls, said spacing element being ixedly secured to said shell Whereb)v said tubular member is made stationary relative to the shell, said tubular member having a helical groove therein extending substantially throughout its length, a rotatable slotted tube extending ber for limiting the upward movement or" said slotted tube. l

In testimonj)v whereof I allix my signature.

WILLIAM C. S. MAYS.
